Ok. To add. I was running klipper before the change to mercury one. I was using the stock X/y motors before, but now I'm using the motors from the kit.

#

No noise before.

#

So is it the motors?

#

Is it the linear rails?

#

Stealth chop was 999999999, before.

#

I've deleted it, then
I put it back with 0

#

I can move x 100mm in any direction, with no noise

#

I can move Y in any direction with no noise

#

Homing x and y, individually.
No noise

#

Homing ALL makes noise

#

Something is rattling

#

That (to my ear at least) sounds like an idler, maybe the toothed?

#

I'm always sus about the toothed idlers, though

strong tangle Jul 18, 2023, 1:55 PM

#

Probably depends on the speed of movement. This sounds like a mechanical noise to me, not from the motors.

Yeah, generally not a good idea to mass tag. I know Dutch works every day of the week, for example. And a lot of people really do read these.

Lol

#

Try homing while holding the printer in the air @dreamy night

#

Especially on the diagonal move, let's see if it sounds the same

dreamy night Jul 18, 2023, 2:04 PM

#

Ya. I understand the 12+ hour days 7 days a week. Did it for the last 19 years. So I'm sorry

mint pasture Jul 18, 2023, 2:04 PM

#

It's okay

#

And stealth chop on x and Y at 0?

dreamy night Jul 18, 2023, 2:05 PM

#

Yes 0

#

I tried it deleted to

mint pasture Jul 18, 2023, 2:05 PM

#

Don't delete it

#

Add
interpolate: True

To the stepper x and Y tmc section

#

Then home it while holding it off the table in the air on the diagonal move

#

Let's see

dreamy night Jul 18, 2023, 2:10 PM

#

Ok. I'll try that. (Still at work)

#

I wish the bot would stop tagging me 😂

Any [safe_z_home] section?

dreamy night Jul 18, 2023, 9:43 PM

#

Ok. I moved printhead (ph) to far left an homed x
No noise
Moved ph to far front an homed z
No noise
Did same with home x and y and all
Noise

#

I picked up cube.
Home all noise but not so loud

#

Which was pain 😂

#

Seems to be a vibration?

#

But only when x and y are homing

strong tangle Any [safe_z_home] section?

#

Are my "run current" correct? For kits motors

#

Belts too tight cause this?

strong tangle Jul 18, 2023, 9:48 PM

#

Kit motors as in Honeybadgers'?

dreamy night Jul 18, 2023, 9:48 PM

#

Which doesn't make sense. I'd assume it would happen all the time

#

strong tangle Kit motors as in Honeybadgers'?

Yes

strong tangle Jul 18, 2023, 9:50 PM

#

You use them for A and B? You've specified different run_current on each.
Ditch the hold_current entries and change run_current to 1.0

#

Do you have a [safe_z_home] section or not?

dreamy night Jul 18, 2023, 9:51 PM

#

A and B ?

#

As in config?

strong tangle Jul 18, 2023, 9:52 PM

#

stepper_x and stepper_y...

dreamy night Jul 18, 2023, 9:52 PM

#

Yes I labeled them stepper_x and stepper_y...

#

strong tangle Jul 18, 2023, 9:54 PM

#

There's no other way you can label them. However, logically, in a core-xy machine there isn't a distinction of a stepper for the X axis and a stepper for the Y axis. They are instead referred to as A stepper and B stepper.

Ok

strong tangle Do you have a [safe_z_home] section or not?

Idk what a safe z home is

Post your config here for me please

OK. Your homing speed (going towards the endstops) is 75mm/s, and when going towards the center, the movement is 200mm/s, as stated in this section -

home_xy_position = 213, 185
speed = 200
z_hop = 5
z_hop_speed = 20

#

My theory is that movement at the higher speed is noisier, for some reason which we will try to detect later.
Find the [safe_z_home] section and change the speed to be the same as your homing speed under [stepper_x], which is 75

dreamy night Jul 18, 2023, 10:06 PM

#

after going to 0/0

#

it goes to center.... there sno noise

strong tangle Jul 18, 2023, 10:08 PM

#

Is there any change from the video you posted when you created this thread?

dreamy night Jul 18, 2023, 10:11 PM

#

safe homing is in here

📎 bed_leveling.cfg

strong tangle Jul 18, 2023, 10:12 PM

#

Great. Set that to 75 to match the speed. save, restart, home all, provide feedback.

dreamy night Jul 18, 2023, 10:13 PM

#

Speed is definitely slower.
So sound is lower

#

See video

#

Moving Y from 0 to 350, 350 to 0.
No noise.

strong tangle Jul 18, 2023, 10:19 PM

#

Issue the command G1 X100 F6000 on the UI's console. This will move the toolhead to X coordinate 100 at a speed of 100mm/s.
Then, issue the command G1 X250 F12000, this would move the toolhead at 200mm/s. Is it the same noise as when the toolhead was homing before?

dreamy night Jul 18, 2023, 10:19 PM

#

Same with x

#

Ok. Give me a second. To do this

strong tangle Jul 18, 2023, 10:21 PM

#

dreamy night Moving Y from 0 to 350, 350 to 0. No noise.

When doing it from the UI you depend on this UI configuration entry -

dreamy night Jul 18, 2023, 10:23 PM

#

No noise

#

Smooth

#

If I'm going to guess.
Slower speeds showing resistance

strong tangle Jul 18, 2023, 10:32 PM

#

Meaning?

dreamy night Jul 18, 2023, 10:33 PM

#

I just changed numbers to 20000 and there wasn't anything

#

So slower shows resistance.
Like tight belts or bearing. Easier

#

Idk.

#

Sorry to bother you.

strong tangle Jul 18, 2023, 10:35 PM

#

Don't worry about that. I just don't understand what you're saying

#

After changing the speed in the [safe_z_home], can you reproduce this noise or not?

dreamy night Jul 18, 2023, 10:37 PM

#

Yes. But it's lower.

#

High speed of 20000 super quiet

#

G1 X100 F20000

strong tangle Jul 18, 2023, 10:41 PM

#

F20000 equals 333mm/s, your specificied max_velocity under [printer] is 300mm/s.
In any case, you may want to revisit this when your machine is print-ready and tuning for speed, etc. I'm not sure what made this noise specifically for that movement at that specific speed.

#

Also if you haven't removed the hold_current entries from all [tmc2209 stepper_] sections, and changed the run_current to 1.0 on [stepper_x] and [stepper_y] yet, do so.

dreamy night Jul 18, 2023, 10:42 PM

#

Ok. I'll carry on with the "step"

strong tangle Jul 18, 2023, 10:47 PM

#

If you want to try and reproduce this in the same diagonal movement as done when homing, these are the commands you can try -
G1 X360 Y410 Fxxxx
G1 X213 Y185 Fxxxx

Change the number after the F to whatever speed (feedrate) you want. It has to be specified in mm per minute, so multiply whatever mm/s value you want to test by 60.
